Enhanced spectrum broadening of ultrashort laser pulses is investigated within a hollow core waveguide filled with a mixture of krypton and nitrogen gases. Nitrogen gas is injected at the front end of the waveguide, while krypton gas is introduced at the back, resulting in efficient extension of the spectrum broadening towards shorter wavelengths while maintaining the longer wavelength range.
